getWriteableName
Description copied from interface:NamedWriteableReturns the name of the writeable object- Specified by:
getWriteableNamein interfaceNamedWriteable
-
getCount
public long getCount() -
getMin
public double getMin() -
getMax
public double getMax() -
getAvg
public double getAvg() -
getSum
public double getSum() -
getMinAsString
- Specified by:
getMinAsStringin interfaceStats- Returns:
- The minimum value of all aggregated values as a String.
-
getMaxAsString
- Specified by:
getMaxAsStringin interfaceStats- Returns:
- The maximum value of all aggregated values as a String.
-
getAvgAsString
- Specified by:
getAvgAsStringin interfaceStats- Returns:
- The avg value over all aggregated values as a String.
-
getSumAsString
- Specified by:
getSumAsStringin interfaceStats- Returns:

value
Description copied from interface:NumericMetricsAggregation.MultiValueReturn the result of 1 value by name- Specified by:
valuein interfaceNumericMetricsAggregation.MultiValue- Specified by:
valuein classInternalNumericMetricsAggregation.MultiValue- Parameters:
name- of the value- Returns:
- the value
-
valueNames
Description copied from interface:NumericMetricsAggregation.MultiValueReturn an iterable over all value names this multi value aggregation provides. The iterable might be created on the fly, if you need to call this multiple times, please cache the result in a variable on caller side..- Specified by:
valueNamesin interfaceNumericMetricsAggregation.MultiValue- Returns:
- iterable over all value names
-
getLeaderReducer
Description copied from class:InternalAggregationReturn an object that Reduces several aggregations to a single one. This method is called whenInternalAggregation.canLeadReduction()returns true and expects an reducer that produces the right result.- Specified by:
getLeaderReducerin classInternalAggregation
-
finalizeSampling
Description copied from class:InternalAggregationCalled by the parent sampling context. Should only ever be called once as some aggregations scale their internal values- Overrides:
finalizeSamplingin classInternalAggregation- Parameters:
samplingContext- the current sampling context- Returns:
- new aggregation with the sampling context applied, could be the same aggregation instance if nothing needs to be done
